Grandiflora rose plant named Twoloy

ABSTRACT

A new grandiflora rose plant producing pink flowers.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of roseplant of the grandiflora rose class which was originated by my crossingas seed parent the variety known as `Brion` and as pollen parent anunnamed and unpatented seedling of my creation. The varietaldenomination of this new rose is `Twoloy`.

Among the novel characteristics possessed by this new variety whichdistinguished it from its parents and all other varieties of which I amaware are its clusters of pink flowers borne on a plant particularlysuitable for use in gardens. Flowers open well and are long lasting onthe plant and after cutting. The new variety is also characterized byits health, vigor and flower production.

Asexual reproduction by budding and rooting of cuttings of the newvariety as performed in Glenn County, Calif. and Kern County, Calif.,shows that the foregoing and other distinguishing characteristics cometrue to form and are established and transmitted through succeedingpropagations.

BRIEF DESCRIPTION OF ILLUSTRATIONS

The accompanying illustration shows typical specimens of the vegetativegrowth and flowers of the new variety in different stages of developmentand depicted in color as nearly true as it is reasonably possible tomake the same in a color illustration of this character.

DESCRIPTION OF THE NEW VARIETY

`Twoloy` is an unusually fine grandiflora rose of pink flowercoloration. It is especially well suited for growing outdoor in gardens.The new variety blooms freely and continuously under natural growingconditions on a tall, upright plant in clusters of up to twelve largeblooms. `Twoloy` also does well on its own roots.

The following is a detailed description on my new variety, with colorterminology in accordance with The Royal Horticultural Society ColourChart (R.H.S.C.C.). The terminology used in color description hereinrefers to plate numbers in the aforementioned color chart.
